...New AVIATION...

.SYNOPSIS...
Issued at 150 PM PDT Tue May 28 2024

Near seasonal temps inland again today with the coast remaining
cool under a well-formed marine layer. Pleasant weather continues
through the week with an inland warming trend.

&&

.SHORT TERM...
(This evening through Wednesday)
Issued at 150 PM PDT Tue May 28 2024

The afternoon forecast update mostly fine-tuned the winds over the
marine environment, while the overland forecast remains on track.

Expect mostly sunny skies into the evening for all but the coastal
Monterey and Half Moon bays areas. The earlier clearing for some of
the more interior areas will make this afternoon slightly warmer
than yesterday, and act as the start of our mid-week warming
trend.

While the coast remains cool, areas inland will warm Wednesday
with the more interior valleys breaking into the mid to upper
80s. Luckily overnight lows mostly stick to the 50s, allowing for
relief from the heat.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 150 PM PDT Tue May 28 2024

Thursday looks to offer the warmest temperatures of the week as
inland areas break into the 90s, but the immediate coast looks to
remain in the 60s. Again with some fair overnight relief. The
patter shifts into the end of the week, allowing for a slow and
steady cooling trend into the weekend.

The extended forecast offers another, similar warming trend
arriving Monday and Tuesday next week. Temperatures from this
warming trend look to peak again in the 90s for the more interior
areas, while the coast sticks to the upper 50s and low 60s. This
looks to be followed my a much quicker cooling trend into the
mid-week.

.AVIATION...
(06Z TAFS)
Issued at 1045 PM PDT Tue May 28 2024

Widespread VFR through the TAF period for most terminals with the
exception of Monterey Bay. Models are in good agreement that stratus
is not likely to develop overnight tonight for most regions. Winds
will continue to ease through the night to become mostly light. In
the afternoon tomorrow, onshore winds increase to become breezy,
then ease to become light into the night.

Vicinity of SFO...VFR through the TAF period. Current satellite
shows a cloudless sky. High confidence in maintaining VFR. In the
afternoon of Wednesday, westerly winds increase to become moderate,
and gusting to around 25 knots. Winds then slowly ease into the
nighttime, but do not become light until the mid morning of
Thursday.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Although currently VFR, a small patch of
stratus is developing over the Salinas valley. There is some
agreement amongst models for low cloud development over the region.
However, confidence in development of an MVFR CIG is only moderate.
Current thoughts are that low clouds will likely develop and
intermittently form BKN CIGs over terminals briefly. By daybreak,
clouds should begin to dissipate, leading to widespread VFR. Winds
onshore and breezy in the afternoon.

.MARINE...
(Today through Sunday)
Issued at 1056 AM PDT Tue May 28 2024

Strengthening surface high pressure over the Eastern Pacific Ocean
in addition to an upper-level trough will allow for strong
northwesterly winds to prevail today and tomorrow with gale force
gusts especially possible over the northern zones and outer
waters.  This surface high pressure will weaken and retrograde to
the west  heading into the weekend allowing for northwesterly
winds to  slightly diminish. Significant wave heights will build
to 12 to  14 feet by Thursday with an abating trend set for Friday
into the  weekend.
